    Abstract: Methods and systems are provided for enabling foveal adaption of temporal anti-aliasing within a foveated rendering presentation. A method for rendering a multi-resolution scene with anti-aliasing within a head mounted display (HMD) is provided. The method includes an operation for rendering a scene that includes a series of video frames. The method also includes operations for applying anti-aliasing to a first region of the scene using a first jitter offset and applying anti-aliasing to a second region of the scene using a second jitter offset. Further, the method provides for generating a foveated scene that includes the first region and the second region and for sending the foveated scene to be displayed on a display associated with the HMD, wherein the first region is associated with a higher resolution than the second scene and the first jitter offset is smaller than the second jitter offset, according to certain embodiments.

    Abstract: Methods and systems are provided for using temporal supersampling to increase a displayed resolution associated with peripheral region of a foveated rendering view. A method for enabling reconstitution of higher resolution pixels from a low resolution sampling region for fragment data is provided. The method includes an operation for receiving a fragment from a rasterizer of a GPU and for applying temporal supersampling to the fragment with the low resolution sampling region over a plurality of prior frames to obtain a plurality of color values. The method further includes an operation for reconstituting a plurality of high resolution pixels in a buffer that is based on the plurality of color values obtained via the temporal supersampling. Moreover, the method includes an operation for sending the plurality of high resolution pixels for display.

    Abstract: A method for updating information for a graphics pipeline including executing in the first frame period an application on a CPU to generate primitives of a scene for a first video frame. Gaze tracking information is received in a second frame period for an eye of a user. In the second frame period a landing point on an HMD display is predicted at the CPU based at least on the gaze tracking information. A late update of the predicted landing point to a buffer accessible by the GPU is performed in the second frame period. Shader operations are performed in the GPU in the second frame period to generate pixel data based on the primitives and based on the predicted landing point, wherein the pixel data is stored into a frame buffer. The pixel data is scanned out in the third frame period from the frame buffer to the HMD.
